h5链接在url的hash部分带参数时，链接拼接错误
demo：小程序代码中的链接为
<web-view src="https://xxx.xxxx.com/promotion/index.html#/page02?channel=testChannel01"></web-view>
按道理实际打开的链接为
https://xxx.xxxx.com/promotion/index.html#/page02?channel=testChannel01
但是实际打开的链接为
https://xxx.xxxx.com/promotion/index.html#/page02?&cookieStr=SESSIONID%253D5c1a131cbfc066f3b6b1b856c660d902%253B%2520up%253Dbup%253B%2520uniqkey2%253DRZhczLgfkoQJoTrJS0naFp72CIKw%252BQNdjdZf9%
链接中的参数 channel=testChannel01 被截取了～
